ATX power supply question

[Dave]

Archived from groups: alt.comp.hardware.homebuilt (More info?)

Hi,

I've just purchased a load of bits, including an Antec Sonata case
(lurvily!!) and an Asus A8V-E deluxe motherboard.

However, it appears I have a problem.. well I hope not, but if anyone
can help I'd be grateful.

On the motherboard, there is a 24 pin 'EATXPWR' connector and a 4 pin
ATX12V connector. It says that an ATX 12V specification 2.0 compliant
PSU should be used (which I thought mine was..).

However, on the Antec case/380W PSU, there is a 20 pin (!!) main power
connector, a 6 pin AUX connector and a 4 pin ATX12V connector.

HELP! These don't seem to match up. Any ideas? Do I need a different
PSU? Or is there an adaptor available..

Dave

I just got an Asus A8N SLI-Deluxe... it also has the new EATX 24-pin plug
with the additional 4-pin connector..

I buckled down and got a 510W SLI P/S from PC Power and Cooling.. It has an
adaptor BACK to 20-pin, but I am pretty sure you can't hook up an old ATX
P/S to a 24-pin board.

Another excellent supply is the 480W NeoPower from Antec.. it has connectors
for both 24-pin and 20-pin boards.

Good Luck

Actually, I've been doing some research and I think that as long as your
PCI express power requirements are modest (and mine are-- 380W is more
than enough for 2x80Gb HDDs, 1x FX330 PCI-E fgx card), you can plug the
20 pin connector into the 24 pin connector on the motherboard. I've
emailed Antec to double check, and I'm also just comparing connector
pin-outs, but I think it's ok.

"The reverse combination is also possible, as the 20-pin plugs fit into
the big connector too. "

20 pin pugs do fit into 24pin plugs. My new MB cam with a sticker over
the last 4 pins. It's says to remove the sticker if the power supply
has 24 pin plug.

Just plugged it all in.. and it works. PHEW!
CPU temp around 37degC, ambient inside case around 32degC. Everything
seems to be ok at present, now I just need to install some operating
systems!
